UtahOversize & overweight permits.

These loads are processed only Monday–Friday, 8 a.m.–5 p.m. Mountain time, and approval can take up to 14 days:

• Over 17′6″ high
• Over 17′ wide
• Over 300,000 lb gross

These moves need UDOT region approval of the route; the permit is not valid until all clearances are in:

• Over 17′ wide on secondary highways
• Over 20′ wide on freeways
• Over 17′6″ high or over 175′ long on any public highway
• You arrange utility company clearances and certified pilot cars
• If UDOT sends an employee and vehicle: $40 or the full cost, whichever is greater

UDOT's superload team runs over-17′-wide and over-17′6″-high requests through route-planning software against structure, construction and secondary-highway restrictions. Loads over 18′ high may have to submit a route survey.

Dual-lane trailers (over 10′ wide) that fail bridge validation need UDOT Structures Division clearance; apply before buying the permit.

• Can take 14 business days or longer, depending on route length and structures crossed
• Each approval covers one trip; repeat moves need a new approval

Semi-annual and annual non-divisible oversize permits cover loads up to:

• 14′6″ high
• 14′6″ wide
• 105′ long
• Larger loads need a single-trip permit unless UDOT grants an exception for an annual-permitted vehicle

Single-trip permits are valid for up to 96 continuous hours, semi-annual for 180 days and annual for 365 days.

Get the permit before operating in Utah, except when entering at:

• Northbound I-15, St. George Port of Entry
• Westbound I-80, Echo Port of Entry
• Eastbound I-80, Wendover Port of Entry

Above the police thresholds the permit may require certified police escorts; you schedule and pay for them.

• Over 17′ wide on secondary highways or 20′ on freeways
• Over 17′6″ high or 175′ long on any public highway
• Email the Utah Highway Patrol a letter of understanding (uhp_wle@utah.gov) at least 48 hours before the move

When a load hits more than one Table 3 trigger, follow the most stringent requirement. UDOT may require more pilot or police escorts.

• The Utah Highway Patrol sets the number of police escorts by area, time and difficulty of travel
• Table 3 escort rules apply only to non-divisible loads

Pilot cars escorting a load over 16′ high carry a height-measuring pole made of non-conductive, non-destructive, flexible or frangible material.

Hold a planning meeting before the load moves with the truck drivers, pilot car drivers, and police, UDOT and utility staff as required. Cover:

• Who is in charge
• Routing and permit conditions handed out

A pilot car driver may stop, slow or wave traffic through when needed to protect the public, standing outside the vehicle with MUTCD safety gear and STOP/SLOW paddles or a 24″ red or orange flag.

Convoys need prior UDOT authorization and must meet these conditions:

The permit is not valid unless the vehicle is registered for the permitted weight, or for 78,001 lb or more when the permit allows over 80,000 lb.

Homes over 14′6″ and up to 16′ wall-to-wall wide, on their own running gear, can get a single-trip permit:
